Up to 30% sulfuric acid
Up to 10% hydrochloric, nitric, phosphoric, acetic acid
There are, however, certain chemicals which may attack PET either chemically to cause loss of clarity or dissolution or physically to cause stress cracking.
Sodium hydroxide, THF, benzene
In other words, it does not react and does not transfer its constituents to the content.
